Fresh off the back of a successful Grammy Awards sweep, rapper Kendrick Lamar played his Super Bowl half time show today.

Lamar's performance happened in the midst of an ongoing defamation suit over his song Not Like Us - with Lamar getting in plenty of digs in at Drake before he performed the track.

The performance also featured special appearances by Samuel L. Jackson, Serena Williams and SZA.

Variety executive music editor Jem Aswad says Lamar had to omit an infamous line from Not Like Us to avoid further legal action.

"But he did all the rest of it, and he referenced it, he said something like - 'I want to play their favourite song but they always sue'. And at the end - not everybody noticed this - but in the audience with the light up wristbands, a bunch of fans were seated so it spelled: Game Over. Which it kind of is."
